ADIPOQ and stricture: In observational analyses modelled linearly, a 1 unit log-transformed higher plasma adiponectin was associated with a hazard ratio of 1.51 (95% confidence interval: 1.37–1.66) for heart failure, 1.63 (1.50–1.78) for atrial fibrillation, 1.21 (1.03–1.41) for aortic valve stenosis, and 1.03 (0.93–1.14) for myocardial infarction; levels above the median were also associated with an increased risk of myocardial infarction, and non-linear U-shaped associations were more apparent for heart failure, aortic valve stenosis, and myocardial infarction in less-adjusted models.
